You enter your Server API token for both login and pass.[/quote]

Hi! Thank you very much for your reply, I have never realized that this API token should be filled in “login” and “pass” fields. Now it works.

Now I have questions, How I can run campaign that just sending email to leads, I can’t understand in interface how I can just run mass mail without any extra actions. Just take list of emails and them them simple email template. Where is “run” button? Please help.
